Todd,

When I trimmed my F16 there were no flaps but the undercarriage was down.
Your F16 when you trimmed for level flight it was with undercarriage down or up?
It seems that with undercarriage down it needs some uptrim to keep levelled flight.
And another question, did you have in yours the 3rd fuel tank of 500ml that is installed between the canopy and the engine hatch?
And the last question, what is your tanks configuration? Mine is that the third tank gets empty the last.

Regards
Vince
